So far, Marta has correctly predicted the winner of 6 out of 13 football games. She wants to know how many consecutive games she would have to predict correctly to raise the percent of correct predictions to 65%.
a. Write an equation to represent this situation.
b. Solve the equation. !Show all steps!
c. Answer the question. How many consecutive games must she predict correctly to raise her percent to 65%?
Answer:
Required Answer:-Marta predicted correctly 6 out of 13 football games .
We need to find first Her's Current percentage[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6}{13}}\times 100 [/tex]
[tex]\longrightarrow[/tex][tex]\sf {\dfrac {600}{13}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf 46.15\% [/tex]
Now We need to add x in both denominator and numerator[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6+x}{13+x}}={\dfrac {65}{100}} [/tex]
Simplify use cross multiplication method[tex]\longrightarrow[/tex][tex]\sf 100 (6+x)=65 (13+x)[/tex]
[tex]\longrightarrow[/tex][tex]\sf 600+100x=845+65x [/tex]
[tex]\longrightarrow[/tex][tex]\sf 100x-65x=845-600 [/tex]
[tex]\longrightarrow[/tex][tex]\sf 35x=245 [/tex]
[tex]\longrightarrow[/tex][tex]\sf x={\dfrac{245}{35}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf x=7 [/tex]
So the new rational number[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6+x}{13+x}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6+7}{13+7}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf {\dfrac {13}{20}}[/tex]
[tex]\therefore [/tex] Marti needs to predict more 13 games out of 20 to raise her percentage to 65%.

Answer:
4/5 / 4/9 = 1 and 4/5 mph or B
Step-by-step explanation:
4/5 / 4/9
4/5 times 9/4 = 36/20
36/20 simplified = 9/5
9/5 = 1 and 4/5
Answer:
4/5 over 4/9 = 1 4/5
Explanation:
(Took test)
Step-by-step explanation:
4/5 mile in 4/9 of an hour
0.8 mile in 0.444444444 of an hour
Unit rate: 1.8 miles per hour
0.8 = 8/10 = 4/5
1.8 = 1 4/5
Two numbers differ by 4. The product of the two numbers is 221. What are the numbers?
Answer:
17 and 13
Step-by-step explanation:
Answer:
Step-by-step explanation:
Represent this with two linear equations:
x+4 = y
x * y = 221
substitute for y:
y= 221/x
Plug this back into first equation:
221/x = x +4
x^2 + 4x = 221
x^2 + 4x -221 = 0
Solve this with a quadratic:
x = -17, x = 13
take the values of 17 and 13, which satisfy the given conditions
5x + 8 = 43
What is x
Answer:
x = 7
Step-by-step explanation:
You minus 8 from both sides which becomes, 5x = 35,
35 ÷ 8 = 7
Check work:
5 times 7 = 35.
35 + 8 = 43
The solution is: solve of the equation 5x + 8 = 43 is: x = 7.
Here, we have,
given that,
the equation is: 5x + 8 = 43
now, we have to solve this.
so, we have,
5x + 8 = 43
we minus 8 from both sides which becomes,
5x = 35
we know that, 5 times 7 = 35
Divide 5 on both sides so that the only thing remaining on the left side is the variable x.
so, x = 7
Final Answer: 7
Hence, The solution is: solve of the equation 5x + 8 = 43 is: x =7.

En una hoja de papel cuyo perímetro es de 96 centímetros, se quiere imprimir un volante de manera que el área impresa sea un rectángulo cuyo largo mida el doble del ancho, el margen superior mida 3 centímetros, el izquierdo 5 centímetros y los márgenes inferior y derecho midan 2 centímetros cada uno. ¿Cuál es el perímetro de la región impresa?, ¿cuál es el área?
Answer:
El perímetro de la región impresa es 72 cm y su área es 288 cm².
Step-by-step explanation:
1. Tenemos el perímetro de la hoja de papel:
P₁ = 96 cm = 2l₁ + 2a₁ (1)
Como sabemos el margen superior, inferior, izquierdo y derecho podemos encontrar la relación entre el largo y ancho del rectángulo interno (región impresa) con el largo (l) y ancho (a) del rectángulo externo (hoja de papel):
[tex] l_{2} = l_{1} - (m_{s} + m_{i}) = l_{1} - (3 cm + 2 cm) = l_{1} - 5 cm [/tex] (2)
[tex] a_{2} = a_{1} - (m_{d} + m_{iz}) = a_{1} - (2 cm + 5 cm) = a_{1} - 7 cm [/tex] (3)
El perímetro del rectángulo interno es:
[tex] P_{2} = 2l_{2} + 2a_{2} [/tex] (4)
Introduciendo la ecuación (2) y (3) en (4):
[tex] P_{2} = 2l_{2} + 2a_{2} = 2(l_{1} - 5 cm) + 2(a_{1} - 7 cm) = 2l_{1} + 2a_{1} - 10 cm - 14 cm = 96 cm - 24 cm = 72 cm [/tex]
Por lo tanto el perímetro del rectángulo interno (región impresa) es 72 cm.
2. Ahora para encontrar el área rectángulo interno debemos encontrar el largo y ancho del mismo, sabiendo que:
[tex] l_{2} = 2a_{2} [/tex] (5)
Introduciendo (5) en (4):
[tex] P_{2} = 2l_{2} + 2a_{2} = 2*2a_{2} + 2a_{2} = 6a_{2} [/tex]
[tex] a_{2} = \frac{P_{2}}{6} = \frac{72 cm}{6} = 12 cm [/tex]
[tex] l_{2} = 2a_{2} = 2*12 cm = 24 cm [/tex]
Entonces el área es:
[tex] A_{2} = l_{2}*a_{2} = 12 cm*24 cm = 288 cm^{2} [/tex]
Por lo tanto el área del rectágulo interno (región impresa) es 288 cm².

Clare wants to make an open-top box by cutting out corners of a 30 inch by 25 inch piece of poster board and then folding up the sides. The volume, `V\left(x\right),` in cubic inches of the open-top box is a function of the side length, `x,`in inches, of the square cutouts.
Answer:
V(x) = 4x³ - 110x² + 750x
Step-by-step explanation:
For each side of the base of the open-top box, since x inches is cut out from each side, we have 2x inches removed from each sides dimension.
Since the dimensions of the poster are 30 inches by 25 inches, the area of the base of the open-top box is thus
A(x) = (30 - 2x)(25 - 2x) since we remove 2x inches from each dimension.
Now, the height of the open-top box is x. So, its volume is V(x) = Ax
V(x) = (30 - 2x)(25 - 2x)x
V(x) = (750 - 60x - 50x + 4x²)x
V(x) = (750 - 110x + 4x²)x
Expanding the bracket, we have
V(x) = 750x - 110x² + 4x³
Re-arranging, we have
V(x) = 4x³ - 110x² + 750x
